Abstract: A device for taking a cell smear comprised of an applicator and a swab located on the end portion of the applicator, the swab is used to collect the cellular material when the cell smear is taken. The swab consisting of a material which is soluble in a solvent that has no detrimental effect on, or is innocuous to, the collected cellular material.A method of taking cell smears for diagnostic examination which comprises collecting a specimen of or from the skin, mucous membrane or other body area or surface to be examined by means of a swab, which is described above. The swab is dissolved in a solvent that has no detrimental effect on, or is innocuous to, the collected cellular material in the specimen. A solution is formed containing the cellular material. The cellular material is then diagnostically examined.

Abstract: A micrometer mixer having a rotary cutter with a replaceable shaver means is used to powderize pigment bars and mix it with plastic pieces. The apparatus further has a hopper and chute mechanism and a controllable trigger mechanism to automatically feed the pigment bar to the replaceable shaver means.

Abstract: A novel device is described for unloading and orienting articles, such as cartons, stacked in tiers on a pallet. The device includes a tiltable pallet receiver which receives a loaded pallet in horizontal position and then tilts the pallet and tiered articles thereon onto their sides with the article tiers forming a series of substantially vertical, adjacent stacks. A means is provided for intermittently advancing the pallet and tiers horizontally in a direction away from the receiver when in a tilted position towards a single tier receiver which receives a single vertical stack of tiered articles from the pallet. The tier receiver is horizontally movable for moving the received stack laterally away from the next adjacent stack and support devices are provided for securely holding the stack in the tier receiver and the next adjacent stack in the pallet during this movement of the tier receiver.

Abstract: Apparatus for and process of mining a subterranean granular ore deposit through a well bore where the ore is eroded from the ore matrix by one or more laterally directed jets of fluid, e.g. water, forming an ore-bearing slurry. The apparatus comprises:A. a rotatable tool string having a first fluid passage through which fluid flows downwardly and a first slurry passage through which a slurry of said fluid and granular ore flows upwardly,B. supported therefrom underground a substantially rigid housing containing an outwardly directed cutting jet nozzle for impinging said fluid against said ore to form said slurry and having1. a second fluid passage therein connecting said first fluid passage with said jet nozzle,2. a slurry inlet through said housing,3. a second slurry passage connecting said inlet with said first slurry passage, and4.

Abstract: Apparatus and process for determining and measuring the internal diameter of or the internal wear, pitting or thinning in a hollow pipeline, or the like, normally underground or underwater, whereby changes in the internal surface configuration or internal diameter of the pipeline at various points along its length are measured. The process includes measuring the changes in the internal configuration of the hollow pipeline, at various points along the length thereof and/or around the circumference thereof at various positions along the longitudinal axis thereof, and converting such measurements of changes in the internal configuration of the hollow pipeline into internal diameters or internal wear, pitting or thinning distance values.
